    • Embodiments of the present invention relate to devices and methods for detecting opsonophagocytotic antibodies using detection particles having product-specific detection reagents and having a characteristic spectral feature. Detection substrates, include microwells. Phagocytic cells are grown in the microwells, and a sample of serum or other bodily fluid from a patient is introduced into the wells, along with a set of detection particles, each set having an antigen recognized by opsonophagocytotic antibodies. The detection particles bind to the antibodies present in the sample and the phagocytic cells then take up the detection particles, labeling the phagocytic cells. The cells are then visualized via image analysis, thereby detecting the presence of, and the types of the opsonophagocytotic antibodies in the sample.

    • Embodiments of this invention include image-based systems and methods for detection of one or more analytes. A surface has identifiable analyte-specific capture particle(s) immobilised thereto at any point of an assay, to which different analytes attach due to the affinity of analyte-specific capture molecule(s) linked to the surface of the capture particle(s) for the analyte. Analyte-specific detector molecules with conjugated detection moieties are then attached to the analyte, and a computer assisted, image-based detection system captures images of the capture particles with or without attached analytes and detector molecules. By using different subsets of analyte-specific capture molecules, each subset having a characteristic identifiable feature; it is now possible to perform capture particle-based, rapid multiplex assays of biological and non-biological analytes without flow. These image-based systems can be used to aid in diagnosis of disease, evaluation of therapy for disease, or laboratory investigation.

    • Embodiments of this invention include methods for detecting in vitro the presence in peripheral blood mononuclear cells (PBMCs), and in serum or plasma, of antibodies reactive to and of lymphocytes that are responsive to CNS antigens associated with Multiple Sclerosis (MS). These CNS antigens include, but are not limited to whole brain lysate and the myelin antigens myelin basic protein (MBP), myelin oligodendrocyte glycoprotein (MOG), MOG peptides (MOGps), proteolipid protein (PLP), and PLP peptides (PLPps). Stimulating PBMCs from patients with MS by CNS antigens cause B-lymphocytes to produce antibodies specific for CNS antigen, and causes T-lymphocytes to produce T-lymphocyte-specific cytokines, including interferon gamma (IFN-y), interleukin-2 (IL-2), or interleukin-17 (IL-17). In contrast, stimulating PBMCs from subjects without MS do not produce such responses.
    • 本发明的实施方案包括在体外检测对与多发性硬化(MS)相关的CNS抗原有反应性的抗体和淋巴细胞的抗体的外周血单核细胞(PBMC)和血清或血浆中的存在的方法。 这些CNS抗原包括但不限于全脑裂解物和髓鞘抗原髓鞘碱性蛋白(MBP),髓鞘少突胶质细胞糖蛋白(MOG),MOG肽(MOGPS),蛋白脂蛋白(PLP)和PLP肽(PLPps)。 通过CNS抗原刺激MS患者的PBMC可使B淋巴细胞产生对CNS抗原特异性的抗体,并引起T淋巴细胞产生T淋巴细胞特异性细胞因子,包括干扰素γ(IFN-γ),白细胞介素-2(IL- 2)或白细胞介素-17(IL-17)。 相比之下,刺激来自没有MS的受试者的PBMC不产生这样的反应。
